The line i am talking about is a shotline with a heavy weight. The divers goes down cuts the line from the weight and tie off to the wreck. Really complicated is it not! I am sure diving the anchor line is much better?.

We almost never have currents where i dive but when we do we use a second boat. I do not dive in Jeresy and i am not trying to tell anybody how to dive in your area. I am just telling you how we dive in our conditions. The risk of not finding our line is almost non exsitant as it is placed on a good spot. All the wrecks that are deep that we dive are intact. If we place the line on the bow for example how are you going to miss the line? It is pretty basic to find the bow on the ship is it not? Infact in thosands of dives we have never missed the line. If we would miss the line we got it coverd with chase boats on the surface. I think this is a method that works good and it has for years. Maybee it would not work in your area and i really do not care either. Could you tell me if diving a 400 feet deep wreck how much of the 1/8 inch line you would need and how big a bag you would need if the current is 3 mph? When i dived the H.M.S Brittanic witch is at 400 feet we had currents of up to 4 mph. Big buoys of maybee 600 ib lift got draged down to a depth of 70 feet. I do not think that your Jersey up line system would work here. You would need lift bags of 800ib and probably a thicker line than the 1/8 inch and it would have to bee at least 800 feet long because the current will catch your huge bag on the way up. It would bee pretty much impossible to swim around on the wreck with all this stupid gear. We had CO2 problems from swiming at depth in currents as it was already. And to anchor on the wreck would bee hard because of the depth but if you did and the anchor pulled during the dive you are pretty fucked if the Jersey upline method fails. And one other thing we could not carry all the gas recuiered for the deco as it would bee pretty stupid to swim around on the wreck with 3 deco bottles in a stiff current and add to that your gear of 800 feet of line and a 800ib lift bag. We had to stage the oxygen for this reason. In the advent of not finding the line we had gas drop stations and several saftey diver ready and 3 chase boats Please enlighten me how you would do this with the Jersey up line method.
